Abstract
The present invention is in the field of polymers comprising identifiable tracers by spectroscopic methods such as XRF, IR, NIR and XRD allowing information to be encoded by the polymers, and in particular polymers for conservation, restoration and retouching in artworks, electronics, coatings, plastics, packaging, 3D printing, rubber, and the like.
Claims21
A polymer having one or more functionalities associated with at least one XRF-detectable metal ion, the polymer being grafted with at least one additional polymer.
